Not leaving the window on "tilt" for hours minimises the risk of attracting the burglers. This is taken care of by the locking mechanism of WINFLIP and can be considered as prevention. After the window is closed manually or automatically the contacts in the WINFLIPâlocking become active and trigger a shrill alarm when there is a burglary attempt. The system is thus self-activating. The alarm electronics remains hidden in the window seam. This is not only a visual advantage, but instead is also effective in frightening away the burglers owing to the ideal sound propagation. You do not neet to activate the alarm system and as such cannot generate any false alarms. Through switching-on via the contacts in the locking WINFLIP alarm does not need any rest current. In this way the battery set has a very long life (> 5 years) WINFLIP alarm is naturally active even when the window is completely closed (grip below) and protects your home also during your holidays. The system proves to be especially effective in the daily use through the combination of automatic locking and automatic sharp alarm system.
